The Scottish star wore her signature blonde pixie cut in a loose wave, and injected a splash of colour with a vibrant pink lipstick. 

Looking just as stylish as her mother, Honor wowed in a flowing pink gown with a contrasting orange belt. 

Meanwhile Sandro - who Tilda has been with since 2004 - looked dapper in a black tuxedo and metallic bow tie.

While Tilda was joined by her family for the event, she opted to walk alongside her co-stars, holding hands with Juan Pablo Urrego and the film's director Apichatpong Weerasethakul.

Memoria is the actress' first project with the Thai director. 

The internationally co-produced drama film tells the story of a Scottish woman (Tilda) who begins to experience a bizarre sensory syndrome while she’s travelling through the Colombian jungles.

Apichatpong told La Tempestad last year: 'I wrote this movie with [Tilda Swinton] in mind knowing that she is an actress who needs no explanation.

'In fact, it was she who showed me this character. The experience was very significant and I really appreciate that.'

Tilda, who's real name is Katherine Matilda Swinton, is known for her portrayal of the White Witch in The Chronicles of Narnia: The Lion, the Witch and the Wardrobe - and its two sequels.
